Privacy Policy

Last updated: May 2026

This Privacy Policy explains how MusicalBoard ("we," "our," or "us") handles information when you use www.musicalboard.com and our browser-based music tools (the "Service").

Audio and device processing

Core features use your microphone and audio output through the Web Audio API. Audio capture and analysis run locally in your browser unless you explicitly export or download a file. We do not store your microphone audio on our servers.

Local browser storage on your device

To make tools usable across page refreshes, the Service writes a small amount of data to storage areas that your browser provides on your own device. This storage stays on your machine; we do not read it from our servers, and we do not transmit its contents to MusicalBoard or any third party.

Recorded and uploaded audio (IndexedDB). When you record on the Singing Recorder or upload an audio file for local analysis, the resulting audio bytes plus a small metadata record (sensitivity, playback position, MIME type, timestamps) are written to an IndexedDB database in your browser so playback, pitch trace, and spectrum views can be restored after a refresh. Only one take is kept at a time — a new recording or upload replaces the previous one. Cached takes expire automatically after approximately 24 hours, and the Service additionally attempts a best-effort cleanup when the page is hidden (tab close, navigation away, browser exit). You can also remove the current take and its cached copy at any time using the trash (Delete) icon in the recorder controls.
Tool preferences (localStorage). Settings such as monitor volume, pitch sensitivity, MIDI range, plot overlays, dashboard window layout, scale/metronome configuration, and similar UI choices are saved using the browser's localStorage so the Service feels consistent between visits. These values do not contain microphone audio. You can clear them at any time through your browser's site-data settings; doing so simply resets the tools to their defaults.
No account, no server-side profile. The Service does not require sign-up, and we do not associate the data above with a personal account on our side.

Information we may collect

Technical data such as browser type, device type, and general usage events, including through cookies or similar technologies where applicable.
If you contact us, the content of your message and your email address (or other details you provide voluntarily).

Advertising (Google AdSense)

We may use Google AdSense to show ads. Google and its partners may use cookies or similar technologies to serve ads based on your visits to this and other sites. You can learn how Google uses data in Google’s Privacy & Terms, and manage ad personalization through your Google settings where available.

Third-party services

We may load scripts or assets from third parties (for example, Google for ads or analytics). Those services have their own privacy policies. We encourage you to review them.

Children’s privacy

The Service is not directed at children under 13 (or the minimum age required in your jurisdiction). If you believe we have collected personal information from a child, please contact us so we can delete it.

International users

If you access the Service from outside the country where our infrastructure is hosted, your information may be processed in other countries with different data protection laws.

Changes

We may update this policy from time to time. The "Last updated" date at the top will change when we do. Continued use of the Service after changes means you accept the revised policy.
